BOTTLE AND BOTTLE CAP.

Application filed May 17,

This invention relates to bottles of the type adapted to be closed bythe application of a flexible disk cap to a recess provided in the neckof the bottle to form a seat for the cap.

The ordinary milk bottle is a highly standardized device, having theinside edge of the neck thereof recessed to receive a thin flexibleclosure disk or cap. This cap is com monly made of cardboard, and,unless provided with costly opening lugs or tabs is difficult to removefrom the bottle. Plain caps must usually be pushed in-on'the contents ofthe bottle to open the bottle; and this operation, whether eflected byhand or by use of a sharp pointed tool usually causes some of thecontents of the bottle to be spilled and wasted, and frequently splashesthe contents on to the person opening the bottle.

The main object of the present invention is to provide a milk bottle ofstandard type having the cap seating finish thereof slightly modified toprovide for ready removal of the cap without necessitating the use ofcostly tabs or the employment of sharp pointed tools.

Another object of the invention is to provide bottles of this type witha cap of stand ard size which effects ready sealing of the bottle andwhich can be readily removed by applying the finger nail of the user torotate the cap.

A further object of the invention is to form the necks of these improvedbottles so as to adapt them for use with standard capping machines andwith standard caps, and formed so as to eliminate sharp edges whichwould be liable to be chipped by the capping inachines.

Still another object of the invention is to form the cap raising partsof the bottle neck so as to cause one edge of the cap to rise fasterthan the diametrically opposite edge when the cap is being rotated toeffect its removal. Other objects of the invention will become apparentas the detailed description thereof proceeds.

ferred form ofcap adapted'for use With this bottle.

Figure 6 is a section on line 66 of Figure 5.

The drawings show the neck 1 of a milk bottle, standard externally inevery respect. The top edge 2 of the roll 3 is unbroken throughout itsinner and outer peripheries; and the inner surface of the neck 1 is pro-.vided with a finish of standard type having the usual recess face 4'andshoulder seat 5.

At diametrically opposite parts the face 4 is provided withsubstantially V-shaped recesses 6 and 7. Each. of said recesses is aboutone-thirty-second of an inch deep where it meets the shoulder 5, and itsinclined edges decrease in depth until they vanish imme diately belowthe line wherethe roll of the bottle neck begins. For example, the inclined shoulders 8 and 9 of recess 6 are each about one thirty second ofan inch deep at the point 10 where theymeet shoulder 5; but decrease indepth as they rise to a vanishing point on the imaginary line 11 wherethe roll of top edge 2 begins. This construct-ion presents smooth edgesto the capping machines, and practically eliminates all chance of chipping the bottle neck during the capping operation.

The recess 7 has its shoulders 12 and 13 in clined at a sharper angle toeach other than are the shoulders 8 and 9 of the recess 6. Thisarrangement is provided to cause the side of the cap 14 in contact withthe walls of recess 7 to rise'more rapidly than the diametricallyopposite side in order that the cap may tilt as it rises to'clear theline 12 where the recesses begin, and more readily effect removal of thecap.

The cap 14 may be the ordinary standard cap commonly used in standardbottles. I prefer, however, to useone of standard size and thicknessprovided with diametrically opposite indents 15 and 16 or projections 17and 18 adapted to be engaged by the fingers of a person desiring to openthe bottle by merely rotating the cap on its shoulder seat 5.

I prefer also to provide the cap 14 with an annular groove 19 to permitthe cap to find a proper bevelseat on the shoulder 5 which in standardbottles is usually down wardly and inwardly inclined with all its edgesand corners rounded. I

I also prefer to mill the edge of the cap 14 in order that the cap edgemay yield slightly where it contacts the unbroken face 4 of the finishand thereby may allow the parts and 21 to project into the recesses 6and 7 and form lugs adapted to ride up on the inclined edges of therecesses 6 and 7 when the cap is rotated in either direction to removeit from the bottle neck. I

It will be apparent from the description so far that I have provided amilk bottle stand ard as to size and adapted to be operated upon-by astandard cappingmachine to apply standard caps thereto. The very slightshouldered recesses (Sand 7 can be very readily formed without involvingany great change inthe bottle moulds and without effecting any changewhatever in the standard roll of the common milkbottle neck.

It will also be apparent thatthe caps described herein may be readilyremoved without pressing it inwardly on the contents of the bottle andby mere rotation will be caused to ride up on the inclined edges of therecesses 6 and 7 without danger of spilling the contents of the bottle.

lVhile I have shown the bottle as provided with only two oftheserecesses, it must be understood that this invention is not to be limitedas to the number thereof. It must also be understood that while I haveshown and described the diametrically opposite re- ,cesses as havingshoulders of different-inclinations that identical recesses may be used.

7 It will also be understood that the invention is not limited to usewith the particular caps shown anddescribed herein and that the bottledisclosed herein is designed for use with standards caps of any ordinaryor desired construction.

What I claim is:

1. A bottle having a shoulder in the neck thereof, a cap seated on saidshoulder, and cooperating means formed on said neck and cap to raise thecap on said shoulder by rotation of the cap in either direction.

2. A'bottle having a shoulder in the neck thereof, a flexible capseatedon said shoulder, and cooperating means formed on said neck and cap toraise by rotation of the cap in eitliei direct on.

- 8. A bottle neck having a shoulder formed below the top edge thereofand having a recess formed therein and extending from said shouldertoward said edge, a flexible cap seated on said shoulder and having apart thereof projecting into said recess, said recess having oppositelyinclined shoulders adapted to engage said part and raise the cap fromsaid shoulder by rotationof the-cap in either direction.

a A bottle having a shoulder in the neck thereof, .and'havingdiametrically opposite 'V-shaped recesses formed therein and extendingfrom said shoulder toward the top edge of :said neck, a

flexiblecap seated on said shoulthe cap from said shoulder 'tated ineither direction to raise the cap from said shoulder.

5. A bottle having a shoulder in the neck thereof and havingdiametrically opposite V-shaped recesses formed therein and flaringupwardly toward the top edge of said neck, a flexible cap seated on saidshoulder and having diametrically opposite parts projecting into saidrecesses and adapted to engage the edges thereof when the cap is rotatedin eitherdirection to raise the cap from said shoulder, and means onsaid cap to rotate the cap in either direction. j

6. A bottle having a shoulder in the neck thereof, a flexible cap seatedon said shoulder and being provided with an annular groove to causeupward tilting of the edge of said cap when seated on said shoulder,means on said cap adapted to be manually operated to rotate said cap,and cooperating means formed on said cap andbottle neck to effect theremoval of said cap from said neck by rotation of the cap.

7. A bottle having a shoulder in the neck thereof, a flexible cap seatedon said shoulder and being provided with an annular groove to causeupward tilting of the edge of said cap when seated on said shoulder,means on said cap adapted to be manually operated to rotate said cap,and cooperating means formed on said cap and bottle neck to effect theremoval of said cap from said neck byrotation of the cap in eitherdirection.

8. A milk bottle, having a neck provided with a standard roll and with ashoulder below the rolled edge thereof, the inner periphery of said neckbeing provided with V-shaped recesses having sides thereof flaringupwardly from said shoulder toward said edge and decreasing in depthfrom said shoulder to a vanishing point at the beginning of the roll ofsaid edge, a flexible cap seated on said shoulder and having projectionsextending into said recesses, and means on said cap for rotating saidcap to cause said projections to ride up on said side when the cap isrotated in either direction.
